PEN-EXTRACTOR.

SPECIFICATION forming part of/ Letters Patent No. 429,218, dated June 3, 1890.

Application iiled March 7, 1890. Serial No. 343,069. (No model.)

To @ZZ whom it may concern:

Be it known that I, JAMES MCELROY, a citi zen of the United States, residing at Madison, in the county of Jefferson and State of Indiana, have invented certain new and useful Improvements in PenI1Xtractors, of which the following is a description.

My invention consists in a new and im.-

proved pen-eXtractor or device by means of' which pens can be readily and conveniently drawn out of a pen-holder without soiling or cutting the fingers, as will be hereinafter fully described and claimed.

Referring to the drawings, Figure l shows my invention as applied to use. Fig. 2 is a perspective view of the parts separated from each other. Fig. 3 is a longitudinal section of Fig. 1.

The saine letters of reference indicate corresponding parts in all the views.

Referring to the several parts by letter, B indicates the base or stationary piece of my device, which may be secured in operative position either to the side of an inkstand, to the desk, or to any convenient form of paperweight or other position that may be desired by the user. This base-piece B is formed at its upper end with an aperture b, through which passes a screw C, by means of which the base is secured in position, and at its lower end the base is formed with a projection b', having a recess b2, through which passes a small screw b3, which serves to secure and steady the lower end of the base. The base is formed with the transverse shoulder B which is preferably curved in the direction of its length, and which is further formed with the concave recess B2, as shown, designed to lit the curvature of the pen.

A indicates the cain or pivoted piece of my device, being formed with a central aperture a, through which passes loosely the pivotscrew C, the cam turning on such screw. The lower curved end and the pivoted cam A are convex in cross-section.

The shoulder B and the lower end of the cam A are both curved eccentric-ally from the common center formed by the screw O-that is to say, the right side of the shoulder B" curves up a little higher than its left side, while the right side of the lower end of the cam curves down a little lower than it-s left side, as will be readily seen by reference to the drawings. The result of this construction is that when it is desired to remove a Worthless or other pen from a pen-holder it is only necessary to slip the pen in between the stationary shoulders B and the lower end of the pivoted cam A, when a pull on the holder will cause the clamp or cam A, in connection with the shoulder B, to automatically seize the pen and bind the same iirmly, and thereby pull it out of the holder as the holder is withdrawn by the hand.

The concave form of the groove 'or recess B2 in the shoulder B and the convex shape of the lower end of the cam A fit the curvature of the pen snugly and give a iirm hold on it, while, owing to the diagonal or eccentric curvature of the shoulder and the lower end of the cam, the harder the pen is pulled to the right the firmer and tighter will it be grasped between the cam and shoulder, so that any pen can be drawn from a holder, no matter how much it may have become rusted or set in the holder.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of my device will be clearly understood.

It will be seen that this device is simple in construction, that it can be secured in any position that may be considered most desirable, and that it is exceedingly convenient in use.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of the vertically-disposed base-plate provided on its outer side with a horizontal shoulder, the surface of said shoulder being transversely concave, and the cam mounted on the base-plate above the said shoulder, the lower end of said cam being transversely convex, as set forth.

2. The combination of the base B, formed with the upper aperture, the lower recessed projection b', and the transverse curved shoulder B formed with the concave recess, the pivotk and retaining screws, and the pivoted cam A, formed with the curved lower end convex in cross-section, substantially as set forth.

JAMES MCELROY.
